To aZZ whom it may concern:

Be it known that 1, (MIKE. ELZEY, a citizen of the United States, residing at Akron;

in the county of Summit and State of Ohio, have invented new and useful Improvements in Billiard-Cue Machines, of which.

cost and which in use will provide means whereby a billiard one tip may be quickly and accuratel shaped.

Another object of the invention is to provide a machine for treating billiard. cue.

sticks and particularly the tip portion thereof for the purpose of shaping and finishing same subsequent to the operation of adhesively securing a tip thereto.

ll further object of the invention resides in the provision of a machine for finishin and dressing the striking end of a cue stic to smooth and remove all roughness from the one tip and to reduce the sides of the stick adjacent the tip and the tip to the same plane. I

A still further object of the invention has reference to a machine for dressing the striking end of a cue stick in which is provided a rotatably mounted wheel with spaced tip receiving grooves in the periphcry thereoi and with abrasive or polishing su stance positioned in said grooves an upon the operating faces of the wheel. The

abrasive substance upon one side of the wheel and the adjacent groove being of a courser nature relative to the opposite wheel side and groove to enable the one stick and tip first to be treated for removing the rough projections and surface and then ground to a fineness to provide an abrasive-- y smoothed surface'on the stick and tip with the adjacent sides of the stick and tip eatendin in the same plane.

A stil further object of the invention contemplates a cue stick and tip finishing machine wherein there is provided a rotatably mounted abrassive wheel and an adjustable clamp and carriage for carrying a one stick with the one stick and clamp to tatably suspended in the carriage, whereby during the finishing or grinding operation on the one stick, said stick rotates at a rate of speed less than the rotation of the grinding or abrading wheel.

The invention is embodied in a compact machine mounted upon a table or other support and preferably embodying an electric motor for operating a rotatable abrading Wheel and a rotatable clamp for supporting a one stick with the carriage upon which the one stick clamp is mounted, being adj ustable both longitudinally and transversely of the machine support, whereby the terminal endof the cue tip and sides of the tip and adjacent portions of the stick are presented for grinding operation upon the peripheral and side faces of the abrading wheel.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and association of parts to be hereinafter more fully described and then claimed.

In the accompanying drawings forming a part of this application and to which reference is had by like characters which are employed to designate corresponding parts throughout the several views 2-.-

Figure 1 is a perspective view of the billiard cue finishing machine constructed in accordance with the present invention, showing the. machine supported upon a table with an electric motor for operating the abrading or grinding wheel and for rotatinfg a cue stick clamp Within a longitudi- -nally and; transversely adjustable carriage.

'Figure 4c is a cross sectional view taken on line 4-4: of Figure 1, showing the worm shaft for rotating the cue stickclamp and the:i shifting screws for the clamp carriage, an

Figure 5 is a detailed sectional view taken on line 55 of Figure 1, showing the side faces oil the abrading or grinding wheel covered with an abrasive substance with the peripheral grooves in the wheel for finishin the terminal ends of the cue tip.

Tiriefly described, the present invention aims to provide a novel machine extremely simple inpoint of construction and one that is inexpensive to manufacture for the purpose of finishing cue stick tips.

In the art in which this invention resides' a one tip of leather or any suitable material is adhesivel secured to the end of a cue stick and c amped thereto under sufiicient pressure and for a sufiicient length of time to cause the tip to be adhesively retained upon the stick. The tips employed are as a rule larger in diameter than the cue stick and project beyond the sides of the stick, leaving a rough edge at the point of connection of the tip and stick. While in many instances the clamp emplo ed for mounting the tip will slightly injure the sides of the stick. This machine has been designed for resurfacing the sides of the stick adjacent the cue tip to remove all defects from the stick and also for grinding the sides of the tip to bring the same into the same plane with the stick as well as resurfacing the end of the tip to present an entirely smooth and continuous surface on the tip and stick.

structurally, the machine is designed for mounting upon a table or other support with driving means, preferably a motor having 'a belt connection with a rotatably mounte abrading or grinding wheel. A carriage is supported on the table and is adjustable both transversely and longitudinally thereof. The carria e supporting a rotatable clam operated y said motor, so that by suitable adjustment of the carriage, the rotatable clamp is shifted toward and away from the opposite sides and periphery of the abrading wheel... It is preferably desired that the periphery of the abrading wheel be provided with two or more circumferential grooves wit-h abrasive substances of the desired fineness placed in each of said grooves and upon the sides of the Wheel so that the one tip and stick may first be treated to remove the rougher surface and then finished by cont-acting with a'finer abrasive substance.

Referring more in detail to the accompanying drawings and particularly to Figures 1 and 2, there is illustrated a billiard cue finishing machine embodying a support,

- preferably in the form of a table inpIuding a flattop 1 mounted upon corner legs 2 a source of motive power 3 being positioned ,at one end of the table having a belt connection with an abrading wheel 4, at the opposite end of the table with an intermediate transversely and longitudinally adjustable ca'rriage 5, operatively connected with said motor for supporting a cue stick to be movable toward and away from the abradinv wheel.

carried by-a shaft 6 journaled on brackets 7, the wheel being rotated through the medium of a .pulley 8 fixed to the shaft 6ad-,,

jacent the brackets 7 and over which pulley the belt 9 from the motor shaft 3' extends, to provide abrasive or grinding means for first removing the rough surfaces from a cue tip and stick and finally finishing the same to a perfect smoothness. The periphery of the wheel 4 is provided with two or more circumferentially extending circular channels or grooves 10 arranged in spaced relation on the wheel as clearly illustrated in Figure 5. The opposite sides of the wheel 4 are covered with abrasive substance 4" and 4 of relatively light and heavy nature, while the peripheral grooves 10 also receiveabrasive substances 10 and 10", the abrasive substance 1O corresponds to the abrasive substance 4, while the abrasive substance 10 and 4 are of like nature. I i

'F or the adjustable carriage and base plate supporting the cue stick clamp, attention is particularly directed to Figures 1, 3 and 4. the table top 1 being provided with a longitudinally extending rib 11 upon which a carriage base plate 12 is slidably mounted and connected thereto by the dovetailed side walls 13. To provide, for the longitudinal adjustment of the base plate 12, relative to the table top 1, a screw 14 provided with an operating handle 14' is anchored in the rib 11 against longitudinal movement and, with the upper side thereof as shown in Figures 3 and 4 engaging the threads 15 in a longitudinal groove formed in the bottom face of the base plate 12 overlying the rib 11. By operating the screw handle 14, the engagement of the screw with the base plate 12 will shift the base plate longitudinally of the table top in the desired direction. The clamp carriage proper, includes a bottom plate 16 having a cross slot formed in the lower face thereof to receive the transverse rib 17 carried by the upper face of the base plate 12 with the dovetail connection 18 between the rib 17 and plate 16. An adjusting screw 19 provided with an operating handle 19' is anchored against longitudinal movement in the base plate 12 with the upper side thereof engaging the threads 20 in a transverse groove formed in the bottom face of the plate 16. It will also be seen that, while the base plate 12 is longitudinally adjustable of the table top, the bottom plate 16 of the carriage proper is independently adjustable transversely of the table.

The one stick clamp is more clearly shown in Figures 1, ,3 and 4, the clamp includin'g associated with each end of the sleeve 21 for retaining a cue stick rigidly mounted therein and includes a sleeve 24 internally threaded for engagement with the exterior threads 21' upon the clamping sleeve with the outer end of the sleeve 24 carrying an inwardly directed flange 24 with a passage opening 25 centrally thereof for the cue stick. A series of clamping do'gs or levers 26 are pivotally mounted in slots provided in the ends of the clamping sleeve 21 inwardly of the chuck sleeves 24 for radial moveinent so that when the chuck sleeves 24 are screwed home to clamping position the dogs 26 are moved inwardly for engagement with the cue stick to retain the stick rigidly mounted within the clamping sleeve. The cue engaging faces of the clamping dogs 26 are provided with a cushion 26' of rubber or similar material which will ermit the cue to be firmly clamped in t e chuck Without injury to its surface.

To eflect rotation of the clamping sleeve, a pinion 27 is keyed to the sleeve 21 intermediate the bearings 22, while a worm shaft 28 spirally threaded as at 29 in contact engagement with the pinion 27 is journaled in the bearings 30 carried by the carriage plate 16 as shown in Figures 1 and 4;. The shaft- 28 has an end extension 31 upon which a pulle or sheave 32 is splined as at 31'. The bet 9 extending from the motor 3 to the abrading wheel 4 traverses the pulley 32 and is maintained thereon by the side flanges 32 of the sheave 32.

It will therefore be seen that a single motor 3 is employed for driving the abrading wheel and the one stick clamp, the intermediate engagement of the belt 9 with the sheave 32 operating the worm shaft 28 and the pinion 27 keyed to the sleeve 21. In the operation of the device, the chuck sleeves 2d are moved outwardly of the clamping sleeve 21 to permit the insertion of the one stick within the tubular clamp. In screwing the chuck sleeves 24 home, the flange 24' is brou'ght into contact with the clamping dogs 26 and the outer ends thereof are moved inwardly, the chuck sleeves thus forcing .the dogs 26 into clamping engagement with the one stick and thereby securely retaining the stick in the clamp against movement. With the motor 3 in operation and connected to the abrading wheel a and the worm shaft 28, the abrading wheel 4 will be rotated at a rate of speed greater than the rotation ofthe clamping sleeve 21 and by shifting the base 12 and the plate 16 of the carriage in the desired direction, either the tip or side of the one stick may be presented for grinding operation by the wheel 4. Assuming that the abrasive substance 4 and 10" on the wheel is coarser than the substance 4" and 10", the'base plate 12 is shifted longitudinally of the table 1 by the adjusting screw 14:, while the carriage 16 is shifted transversely of the table by the adjustingscrew 19 to resent the cue tip for grinding.

operation within the peripheral groove 10 or to present the side of the tip and adjacent portion of the one stick for contact with the abrading side 4 of the wheel. It will be noted that during transverse adjustment of the carria e late 16, the worm shaft 28 will travel wit tlie carriage,'while the belt 9 of the motor 3 will maintain the pulley 32 in line with the motor and pulley 8, on the wheel shaft 6. When the rough surfaces have been removed from the tip and stick, the carriage and base plate are again shifted to present the stick and tip for engagement with the finishing abrasive portions 4 and 10 of the wheel 4:.

It is notintended that this invention should be limited to the exact details of construction shown as the present embodiment of the invention may be considered only as one illustrative form thereof and while the preferred form is herein shown, it is to be understood that various changes may be made without departing from the spirit and scope of the invention as claimed.
